the strip DRM part was always a plugin for calibre, not a native function. Personally Calibre did amazing work for me always, even if the UI was clunky. When I used a kindle i had it set up to immediately convert everything to a non DRM format and use amazon whispernet (or whatever they're calling it now) to send them automatically and wirelessly to the device. Hard to argue with that kind of flawless performance.
